They said they wanted to party to oppose the 'vapid, old school centrist politics'

What are their policies?

In a statement they said they wanted a new approach and be “the opposite of vapid, old school centrist politics”.

They also wanted to have a “fiercer Green resistance” to both fracking and the HS2 rail link.

Bartley said: "When faced with the environmental destruction of fracking or the spiralling costs of HS2, or the inhumanity of indefinite detention and forced removals of refugees and migrants, we are not afraid to join protestors putting their bodies on the line for what is right.”

He added: “In council chambers across the country, Greens are leading a political revolt against the status quo. We are more determined than ever to take the party to the next level.

“We want to take the Green party on a course to become the third political party in Britain, building on this year’s local election success to get a Green on every council in England and Wales.”

Bartley was elected a Streatham councillor in May 2018 and his lead the opposition on Lambeth council since then.

Berry was elected a Green London Assembly member in 2016 and also came third in the London mayoral race.

She has been a Camden councillor since 2014.

She said: “We will be championing a people’s vote on Brexit, tackling climate breakdown, ensuring everyone has the right to a safe warm home and fulfilling work that translates to more time off with our families, not more unemployment as automation grows.

“We are the only party who can be trusted to stand up for citizens in our nations of England and Wales, instead of the interests of big business or millionaires.”
